Up for sale is a Calibrated Laser Power Meter which can go up to 120mW, or even higher if you use a ND filter which I will include. It is known as the HLPM and made by laserbee. It has only about 20 minutes of use on it, most of the lasers I bought are too high power to use with this so I am upgrading to a Laserbee I. This unit works perfect though and I'm asking $25 for the power meter with an included a ND filter which cuts light in half to detect powers up to 240mW (looses some accuracy using ND filter). (plus actual shipping, probably only a few buck in the US).

haha lol I'm really happy, it's the first time I get a real good offer from this forum and now I'm feeling great

Used by MisterWilling, built by Laserbee and shipped and checked by Daguin= epic win

This can't go bad

@Misterwilling: since Daguin already have to send me a package, send him the LPM and he will ship it to me ^^

I think I can get them easily if you give me the 3 resistors specs. On my campus electronic lab there is a full room of electronic parts to which I have full access, so... xD

Aren't them carbon resistors with 5% tolerance?

Yours,
Albert

The way to find the reduction ratio of your ND filter is to take
a <120mW laser and shine it onto the 120mW LPM Modules sensor
an note the reading...
Then using the same Laser.. place your ND filter in between the laser
and Sensor and take another reading...
The difference is the reduction ratio for that wavelength laser and
that ND filter...

If with this LPM I end up being able to test my 200mW Rayfoss laser I'll for sure be the happiest man in the earth hueihueihuei
